I've been lurking here for a bit and finally have started building a lunetta of my own. This is a whole new world for me and is a lot of fun.

Anyway, here's what I've got going on right now:

A 40106 driving 6 oscillators. Three are completely hooked up and three still need to be wired up to the panel
A 4093 quad gated oscillator
A 4046 pitch tracker
A LM348 based tone generator kit that has been tweaked a bit to turn it into a VCO
The infamous Slacker Melody Generator
A 8 input passive mixer
And finally a WSG (my learn to solder kit )

Combining the melody generator with the pitch tracker is more fun than it should be.

Really nice looking lunetta there; diggin' the knobs too. Very good set up of modules to play with. The pitch tracker to me is like what a fuzz pedal is to an electric guitarist; a simple but powerful sound enhancer. Even just running two separate oscillators into a gating ic like a 4070, 4011, 4001, can produce huge varieties to timbres with the 4046 pitchy.

The problem I have with the 4040 is if you want to use the divisions to trigger drum voices, you will have to invert every output to bring it all into sync. It's a real pain as it increases the IC count or involves a lot of transistors.

If you just want to make beep noises then this probably wont concern you. I wish there was another IC which didn't have this issue. Perhaps there is and I haven't found it yet.

ha! Well there was one thing you posted somewhere which I thought was interesting... although I'm not sure where. It was where you used maybe just 3 IC's in a patch. It was a video I think.

It's easy to get over ambitious with these things. You can do a lot with very little if you choose carefully. There seems to be a convex curve to this Lunetta thing. It gets to the point where adding more ICs does less to the noise than they once did when you had just a handful to play around with. There might be a point of critical mass .

In fact, I have made sounds with just ONE IC which give much more elaborate machines a run for their money in terms of random hands off blip bleep crackle click blooping.

@minus: Probably something like the 4046 pitch tracker video where I ran 2 oscillators into a gate of some kind and the output was fed to the tracker. Tons of variety with just those chips made me rethink how big a lunetta has to be to be "worth it".

I remember many a night trying to come up with something really cool by plugging more stuff in and getting frustrated. In the end, I realized simpler IS better .

Grand statements right? Maybe, but after spending a few years on these like you and I have - affords us some... leeway .

I was going to try to use the 4040 to trigger drums. I hadn't thought about inverting the outputs. That would go against my plans on keeping modules as simple as possible. Plugging it into an R/2R ladder is fun. Provides plenty of beeping - and that makes me happy.
